Description

Tooth extraction wound cover device

The present invention relates to a tooth extraction wound covering device used for dental tooth extraction, particularly a tooth extraction wound covering device capable of covering a tooth extraction wound, so that the tooth extraction wound can avoid being directly exposed to the oral environment, and can relatively reduce the bacterial infection of the tooth extraction wound. Chance of infection.

Generally, when a dentist performs tooth extraction, the dentist will use dental forceps to clamp the crown of the tooth. Then, the dentist will use the dental forceps to separate the root of the tooth through destructive methods such as pulling and turning. on the gums and gums to achieve the purpose of tooth extraction.

After the tooth is extracted from the tooth pulp, the tooth pulp will form a tooth extraction wound and start to bleed, requiring the patient to bite the gauze to stop the bleeding. However, during the process of hemostasis in the tooth extraction wound, the tooth extraction wound will be directly exposed to the oral environment. This makes it easy for food or contaminated materials in the patient's mouth to enter the tooth extraction wound, causing the tooth extraction wound to be easily infected by bacteria and become inflamed. Even when the patient is brushing his teeth or chewing food, the toothbrush or food will hit him. When the tooth extraction wound is exposed, the blood clots solidified after tooth extraction will break away from the tooth extraction wound, which will prolong the healing time of the tooth extraction wound.

The main purpose of the present invention is to provide a tooth extraction wound covering device so that after the tooth is extracted from the gum, the tooth extraction wound covering device can cover the tooth extraction wound to prevent the tooth extraction wound from being directly exposed to the oral environment, and thereby solidifying the tooth after tooth extraction. Blood clots can remain inside the tooth extraction wound. Even when the patient is chewing food, the food will only hit the tooth extraction wound protective device but not the tooth extraction wound. As a result, the coagulated blood clots after tooth extraction will not break away from the tooth extraction wound. Relatively speaking, It can shorten the healing time of tooth extraction wounds.
